LUBRICATING DEVlQl-l FOR HIGH-SPEED AND EXPLOSION MOTdRS.

":EEEGIFICATION forming part of Letters Patent No. 747,767, dated December 1903- Application filed January 23,1903. Serial No. 140.270- (No model.)

To all whom it may concern. Be it known that I, LOUIS RENAULT, a citizen of the French Republic, residing at Billancourt, Seine, France, have invented certain new and useful Improvements Relating to Lubricating Devices for High-Speed and Explosion Motors, of which the following is a specification.

This invention has reference to lubricating devices for high-speed motors, and is now particularly applicable to explosion-motors. In motors of this kind it is not possible to effectually apply the lubricant to the heads of connecting-rods and bearings simply by means of the ordinaryoil-bath, because if this oiling is efiected for a sufticient time and a sufficient quantity of oil is used projections of oil are produced in the interior of the cylinders, which results in clogging of the igni- Furthermore, the greater the speed of the motor the more difthe oil from the heads of the rods and prevents effective lubrificatiou.

The object of this invention is to obviate these inconveniences, and to this end I utilize the action of the centrifugal force of the heads of the connecting-rods by collecting in reservoirs placed in a suitable manner above the bearings the oil thrown out; from the.

heads of the connecting-rods, the said reser voirs serving at the same time as lubricators partly to the bearings, and consequently to these same heads of the connecting-rods.

"In the accompanying drawings, Figure l is a sectional elevation of the gear-case of a motor with four cylinders, taken through the axis of one of said cylinders. Fig. 2 is a longitudinal section of the same, showing the four cylinders.

The gear-case is provided at its upper part with a rib or flange a, forming a reservoir b, and having the form of a gutter, of which the opening is turned from the side of the wall of the gear-case which receives the projections of oil. This gutter communicates with a reservoir c, placed somewhat lower, but above the hearing. In a motor with four cylinders A B O D there exists three reservoirs c d e,

one for each shaft-bearing; but the reservoir 01 of double dimensions is common to two adjacent cylinders B C and is fed by the two adjacent connecting-rods. About thecrankaxle and about the crank-pin of each bearing {is arranged a circular groove or channel 1', adapted to collect the excess of oil flowing out of the bearing. This groove?) communicates by the condnitj with. the head of the con- When the heads leave the oil, the centrifugal force projects the oil whichthe heads have gathered against the walls of the gear-case, and the oil thus projected is gathered in the gutter b. When the quantity of oil is sufii- 'cientl'y large, it flows downinto each of the reservoirs 0 cl 6 corresponding to each of the bearings for the crank-shaft of the connecting-rods; The oil filling the reservoirs c d e lubricates each of the bearingsfg h and the thereby avoiding the accumulation of oil ina in what manner the same is to be performed,

I declare that what I'cl'aim is- 1. In a lnbricator of the class described,the combination with a casing, and a plurality of shaft-bearings'therein, of a plurality of reservoirs disposed above and communicating with said shaft-bearings, and a collecting-gutter ranging lengthwise of the casing and communicating With said reservoirs for supplying them with lubricant collected by said gutter.

2. In a lubricator of the class described,the combination with a casing, and a plurality of shaft-bearings, of a plurality of cranks each provided with a transverse passage and with a collecting-gutter which occupies such relation to one of the shaft-bearings as to collect the lubricant escaping therefrom, a plurality of reservoirs in communication with the shaftbearings, and a collecting-gutter ranging lengthwise of the casing and communicating with the reservoirs.

3. In a lubricatorof the class described, the combination with a casing, a series of shaftbearings therein, and a crank-shaft mounted in said bearings and provided with a series of cranks, of a gutter supported within said casing adjacent to the path of the cranks and adapted to collect the lubricant thrown centrifugally against the casing by the rotation of said cranks, a series of reservoirs commu nicatiug with said gutter and with the bearings of the crank-shaft, and means for conveying lubricant to the crank-pins of the shaft.

4. In alubricator of the class described, the combination with a casing, a series of shaftbearings therein, and a shaft having a plurality of cranks, of a gutter within said casing, a series of reservoirs communicating with the gutter and with the shaft-bearings, and gutters carried bythe cranks of the shaft and operatively disposed to the bearings of said shaft, said gutters on the cranks being connected by inclined conduits with the crankpins of said shaft.

In witness whereof I have hereunto set my hand in presence of two Witnesses.

LOUIS RENAULT.
